Stickies is a virtual post-it notes program that allows you to place sticky notes on your desktop, which will remain where placed until closed - even across reboots. The appearance of the sticky notes can be customized in color, font, transparency and other aspects. The notes can even be sent across a network, synchronized with friends, imported/exported, sent by email or attached to application windows. You can choose to hide or show all notes with a single click from the tray and also recover notes that have been deleted in the past.
Stickies can be hidden (sent to sleep) for a certain period, or until a specified date and time, to act as a reminder. Stickies is probably one of the best sticky note program you can find, it is small, well documented and comes with many useful features.
